BRlDLE-BIT.

SPECIFICATION forming part of Letters Patent No. 394,454, dated December 11, 1888.

Application tiled October 8, 1888. Serial No. 287,507. (No model.)

To LZZ whom it may concern:

Be it known that I, 'lHoMAs BRABsoN, a citizen ot' the United States, residing' at Newark, in the county ot' Essex and State ot New Jersey, have invented new and useful Improvements in Flexible Mouth-Pieces tor Bridle-Bits, ot' which the followingl is a specification.

This invention relates to bridle-bits having flexible mouth-pieces; an d it consists in a novel construction of a bridle-bit provided with a flexible mouth-piece, as is fully described and claimed in the following specification, reference being' had to the accompanying' drawings, in which- Figure 1 is a front elevation of a bridle-bit containing' my invention, the flexible mouthpiece beingl for the most part in longitudinal central section. Fig. 2 is a similar elevation, in which the covering' ot' the mouth-piece is in longitudinal section. The ligure also shows in partial section the connection of one end of the iexible mouth-piece with the bit-ring.

Similar letters indicate corresponding'parts.

The letter A designates a bridle-bit which is provided with a tlexible mouth-piece, B, whose ends are connected, as hereinafter described, to the bit-rings C The flexible mouth-piece B consists of a central flexible core composed of a series of links, D, connected to each other at their ends and constructed by forming a chain of wire links, e e e, as many in number as are required for the length of the chain, and then castingl upon the central part of each link e a block, f, in such a manner that the blocks f cannot slide on the links. The end links, e e, are interlocked with links g g, which connect the combined links and blocks e j with the bit-rings C. The connecting-links g are connected to the bit-rings in such a manner that the bit-rings and the links can freely turn on each other. Two methods ot' accomplishing` this are shown.

In Fig. 1 the links g g are bored out and provided in their outer ends with internal screw-threads, 7L, into which are screwed the threaded ends 'i of eyebolts J, which are secured between the jaws 7tk of the bit-rings in the usual manner.

In Fig. 2 the outer ends of the connectinglinks y g are inserted between the jaws 7: l: of the bit-rings, and are secured by a bolt, L, which passes through the jaws L' k and the link g and is fastened 'in that position, so that the bit-ring's and links can freely turn on each other.

Before the links y g are secured to the bitrings the tlexible core D is surrounded with a covering' ot india-rubber, M, which may be in the form ot' a tube ot' proper size to tit closely upon the` core D. 'lhe ends ot" the rubber covering' are fitted closely over the ends of the core I), where they meet the bitrings, so as to make a tight joint there against the entrance ol' moisture into the rubber and the core I), and in the example shown in Fig'. l the inner ends ot' the eyebolts J are recessed at n n to admit the ends of the rubber covering' within the recess and thus obtain a tight joint.

The blocks j' and links g are in this example cast from iron and are of the same diameter, substantially, so as to make the rubber covering smooth and the mouth-piece ot' unit'orm size.

By casting the blocks upon the wire links e the links e are protected, except the endprotruding portions, from injury by moisture, which might g'ain entrance under the rubber covering M.

'hat I claim as new, and desire to secure by Letters latent, is-

l. The combination, with the bit-rings ot'a bridle-bit, ot' a mouth-piece comprisingl end links, g, a series ot intermediate connected wire links, e, and a block, f, cast upon and around each one of said intermediate links and constituting' an immovable part thereof, substantially as described.

2. The combination, 4with the bit-rings ot' a bridle-bit, ot' end links, g, blocks j, and a series ot wire links, e, passing' centrally through, rigidly tixed in, and projectingl beyond the axis ot' the blocks, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence ot' two subscribing' witnesses.

THOMAS BRABSON.
